Abstract
This document aims to identify and present key issues related to the raw data used in the analysis. It highlights inconsistencies, gaps, or ambiguities in the data structure, content, or processing steps that may impact the reliability and comparability of the results. By systematically addressing these issues, this report seeks to provide clarity on the challenges inherent in the raw data and to propose areas where further refinement, validation, or clarification is needed. The ultimate goal is to ensure a solid foundation for subsequent analyses and to support informed decision-making regarding data preparation and use.Only the squares where the integrity of the area is located on land are considered in the analysis. The analysis has been perform using the cwp grid dataset that can be found : https://github.com/fdiwg/fdi-codelists/raw/main/global/cwp/cl_areal_grid.zip
